perf test session topology: Fix test on s390
[ Upstream commit b930e62ecd362843002bdf84c2940439822af321 ]
On s390 this test case fails because the socket identifiction numbers
assigned to the CPU are higher than the CPU identification numbers.
F/ix this by adding the platform architecture into the perf data header
flag information. This helps identifiing the test platform and handles
s390 specifics in process_cpu_topology().
Before:
[root@p23lp27 perf]# perf test -vvvvv -F 39
39: Session topology :
--- start ---
templ file: /tmp/perf-test-iUv755
socket_id number is too big.You may need to upgrade the perf tool.
---- end ----
Session topology: Skip
[root@p23lp27 perf]#
After:
[root@p23lp27 perf]# perf test -vvvvv -F 39
39: Session topology :
--- start ---
templ file: /tmp/perf-test-8X8VTs
CPU 0, core 0, socket 6
CPU 1, core 1, socket 3
---- end ----
Session topology: Ok
[root@p23lp27 perf]#
